Recommended Posts

Hallo, ein Linsenforum habe ich nicht gefunden, daher erlaube ich mir die Frage hier zu stellen:

 

Hat einer von umgebaute Contax G Linsen für seine M-Leica?

Mich würden persönlöich Erfahrungen sehr interssieren. Evtl. hat sogar eine vn Euch selbst Hand die Linsen gelegt?

 

Wer jetzt mit meiner Frage gar nichts anzufangen weiß, dem lege ich folgendne link ans Herz:

 

Contax G to Leica M Lens Conversions

der führte mich zum Hersteller:

Converted Contax G lens for Leica M Packages | japan exposures

 

Die Idee finde ich sehr interessant, einen Konatktaufnahme habe ich allerdings noch nicht erreichen können.

 

gute Zeit

Sicher sind die Voigtländer Linsen und die ZMs nette Dinger, aber die Contax Objektive haben eine ziemlich an der Leica-Leistung liegende Bildqualtät. Das 45er Planar wäre für mich die universal nutzbare Brennweite. Das 90er hat Lichtstärke 2,8, die gibt es heuer weder bei Voigtländer, noch bei Zeiss.

 

gute Woche

die umgebauten contax-objektive sind nicht gerade schönheiten und über die mechanische qualität und die handhabung sagen die bilder nichts aus. zudem sind die umgebauten objektive nicht so günstig, dass es nicht von fremdherstellern oder auf dem gebrauchtmarkt bessere alternativen gäbe.

 

an der contax übrigens verwende ich die g-objektive sehr gerne und bin von ihrer qualität überzeugt.

Für die Preise kriegt man mit etwas Glück schon fast ein Leica-Objektiv. Ich hab mir die Linsen auch mal angesehen - aber es dann sein lassen.

 

Und wegen der Kontaktaufnahme würde ich dir eine Email an Dirk empfehlen ( sieht contact auf deren Seite ); der spricht auch Deutsch. Vielleicht macht das einiges leichter für dich.

Zoerk in M macht diese Contax G Umbeuten auch . Frage auch da mal nach. IMHO

musst du aber die Linse selbst organisieren.

Nach meiner Meinung "lohnt" es sich ev. beim 21er Contax G

Vielen Dank für Eure Rückmeldungen!

 

Mittlerweile habe ich von Dirk die Info, dass die notwendigen Einzelteile für einen Selbstumbau meiner Objektive nicht vertrieben werden. Ich hatte aus Zollgründen geplant, dort nur die Teile zu beziehen und die Arbeit selbst auszuführen. Wird wohl nix....

 

Mal sehen, was mir noch an Dumm' Zeuch einfällt, das Projekt ist nochg nicht gestorben.

 

gut' Licht & sauberen Sensor

      Hello everyone, here's my review of the new Carl Zeiss Contax G Planar 35mm f/2 FUNLEADER conversion to Leica M.
      This is my first review here so I am not used to the technicalities of posting, please forgive me if I readjust things after I post.
      FUNLEADER Contax G35 to Leica M Conversions

      Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen? Einfach registrieren oder anmelden! I have included the 7artisans 35mm f/1.4 M and the Voigtlander VM 40mm f/1.2, the only lenses in the 35mm zone I own.

      Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen? Einfach registrieren oder anmelden! Disclaimers:
      1. none of the lens makers / converters have been involved in these tests and I have personally purchased all 3 lenses, none of them have been provided.
      2. the FUNLEADER link above contains an affiliate link with a code that will get you a 5% discount (used to be 15%, I hope they bring that back). If you purchase using the link above FUNLEADER says I will receive 10%.
      3. all opinions expressed here are my own and, just like with anything in life (especially photography equipment!), you may have a different one.
      A few bullet points about the tests:
      - done on my Leica M-P typ 240
      - done on a tripod with a 2 second timer to hopefully dampen most vibrations
      - no filters or hoods were used and lenses were extremely clean
      - captured at M-P's base ISO: 200 (with the exception of a few frames captured at 1.2 and 1.4 because 1/4000 was too slow to keep equal exposures so I set the ISO to PULL 100)
      - exposure was manual and the exposure time was adjusted accordingly with every aperture change (generally 2/3 stop) in order to hopefully maintain an even exposure between the samples
      - white balance was on AUTO
      - all focus was EXTREMELY CAREFULLY done using LIVE VIEW at f/2 for each lens, using both the focus peaking and my own eyes to make sure I get the best possible focus
      - focus was redone with every lens change
      - the 40mm was repositioned so that the main subject filled roughly the same size in the photos (as much as possible, the infinity tests obviously show the difference in focal length)
      - most tests were taken all all apertures but since this ended up requiring so much work I only included up to f/8, to be honest I don't think anything past that is relevant
      - all samples processed in Capture 1 PRO with the default output sharpening for screen (any image processor will apply some sort of sharpening from DNG to JPG)
      - I am sharing a Google Drive folder with all DNGs, JPGs, comparisons and misc images, all full size. Please check them out and use them for free, a credit would be nice if you end up posting them. 
      PART 1 / 5
      A morsel of history: if you're reading this you most likely know what this lens is, otherwise this info can be easily found online.
      The G35/2 is supposed to be the "lesser performer" of the Contax G suite, the internet is funny like that, some person deemed it once as not being as stellar as the G45/2 (which is whispered to be one of the best lenses in 35mm photography history) and the internet has taken that and transformed it into "not a good lens" kind of rumour. I am here to prove otherwise.
      Here's a G35 / G45 specs comparison:

      Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen? Einfach registrieren oder anmelden! This 35 together with the Hologon 16mm are the only ones I do not own in G mount. I have shot all the other ones (21/2.8, 28/2.8, 45/2, 90/2.8) on my Contax G2 and adapted on my Sony A7R3 with a cheap Ulata adapter. They are sharp, very sharp wide open. And so light.
      Build quality: without further ado, I think FUNLEADER and Mr. Ding have done an amazing job here: the conversion is incredible, so tiny and lovely, with a great weight and feel. The focus action is nice and smooth and the little focus tab suits the lens. The black paint version is really beautiful, I have always been a black paint / lacquer fan, hence my M-P. This version will get patina with use (unless you're Lenny Kravitz and give it a good rub to look well used). The "gold" version has lovely sharp black engravings and a black focus tab. The focus tabs are really nice, placed at the perfect position where, when pointed straight downwards, the lenses focus at 4 feet / 1.2 meters. I also purchased a "gold" helicoid as I am planning to do a conversion myself. The "gold" helicoid feels like brass and it's a bit of a fingerprint magnet.
      The helicoid has "MR. DING" engraved on the mount. Pretty cool. I did a bit of digging and "Mr. Ding" is their master craftsman, maybe having been part of MGR Production. They are also behind the Bresson Viewfinder magnifier, which I happen to have on my M-P and love.
      I would love to find out more about Mr. Ding, if anyone has info please do share.

      Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen? Einfach registrieren oder anmelden! The weight of the helicoid is 206g / 7.26oz and the whole lens is 266g / 9.38g

      Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen? Einfach registrieren oder anmelden! The lens did have a plastic ring glued on the front, on top of the original Carl Zeiss from markings, but I removed it easily and left no marks. Sorry Mr. Ding, I prefer the original Carl Zeiss engravings.
      The original lens hood of the G35 / G45 fits nicely, but I have the champagne version and I personally don't think it works with either the black or the gold version. I might spray paint it with a glossy enamel.
      Honestly, it looks amazing on the M-P. It is a gem of a little lens and a great performer.
      Customer service: excellent, very responsive, I had quite a few questions for them and they replied very quickly.
      Packing: excellent, pragmatic, not fancy.
      Shipping: wowsers, the lens was in my hand in Vancouver BC Canada in 6 days, dayum!
       
      PART 2 / 5: colour, focal length, sharpness close and mid distance
      Two notes about colour and focal length:
      - colour - the G35/2 renders the most accurate and neutral colours, next is the VM 40/1.2, while the 7artisans 35/1.4 M renders quite warm
      - focal length - the G35/2 is a little wider than the 7artisans 35/1.4 M, I wonder what their real focal lengths are. Please do share if you happen to know.
      Sharpness: the G35/2 is very sharp wide open, it nearly matches the VM 40/1.2 at f2, actually honestly we are splitting hairs between the G35/2 and VM 40/1.2. Keep in mind that the VM starts at 1.2, so from a lens design pov it has a lot of room to be sharp at f2. It's quite a feat how consistent the G35/2 is all the way up to the widest apertures. The G35/2 is sharper than the 7artisans 35/1.4 M at every aperture. I was surprised as well. In all honestly, I really love the 7artisans lens, it has a really nice 3d pop and the built is absolutely amazing.
      Check out these 100%s of this starling at f2! I used live view, there's no way to nail that in the viewfinder patch, I also took a bunch of shots and these were the best 4, maybe out of 12 or so.
      100%

      Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen? Einfach registrieren oder anmelden! I have done a few test sessions but not included all here (so much to process and compare), so here are a few. Before every comparison chart you will see a half size G35/2 image at f2, for no reason really other than to show you what the whole scene looked like.

      Focus shift: I did not test for it, but from my walks it seems to be fine.

      CONCLUSION:
      The Carl Zeiss Contax G Planar 35mm f/2 is a gem. Coming from great heritage, it is now encased in an amazing conversion from FUNLEADER for our Leicas. The G35/2 is an honest lens, you won't find clinical sharpness here, but since you're reading this you're probably not looking for that, but for the resurrection of a highly underrated Carl Zeiss optic. The G35/2 renders the world gently with neutral colour rendition, pleasant bokeh and a sprinkle of pop. The tiny form has a great weight and feel and it simply looks incredible on a Leica. The black paint version is shiny and will brass while the "gold" version has lovely sharp black engravings (bit of a fingerprint magnet though). I honestly look at my camera sitting on my desk now and hear the whispers: "take me out and make photographs". Well done FUNLEADER and Mr. Ding, hat's off to you.
      Just like the original little piece of history it now protects and focuses, the FUNLEADER conversion will also be remembered as a gem amongst the connoisseurs.

      Hallo zusammen,
       
      ich dachte bisher, es gäbe nur den m39 auf M-Mounth Adapter, welcher eine Kopplung an den Entfernungsmesser hat.
       
      Jetzt sehe ich ab und zu Verkaufsanzeigen, in dem Minolta MD oder Contax/Yashica Objektive mit einem Adapter angeboten werden, bei dem im Text angegeben wird, dass die Kopplung an den Entfernungsmesser perfekt funktioniert.
       
      Gibt es solche Adapter fertig zu kaufen, oder handelt es sich um "angefertigte" Adapter, bzw. geänderte? Man hört oder liest so garnix drüber?
       
      Ich möchte gerne das ein oder andere 1,4er zu meinem Cron an der M probieren.

      I've always wanted a really wide angle lens. I would have bought one for my old Contax G, but as you might recall, the 16 F8 was hugely expensive, and also vignetted like crazy. Times have changed.
       
      The pix taken with this lens on Flickr convinced me it would be something special. Looking forward to receiving the machine in a week or so,

      I had my lenses adapted to the M9 (e.g. distance / focus of each lens was syncronised to this particular M9) now I am going to buy a M240, I am wondering if the distance / focus will be correct to the M240 too
      Does anyone have appropriate experince ?
       
      Thank you very much for your reply

      Bei ebay wird ein Adapter für Hasselblad-Objektive angeboten:
       
      Leica S2 DSLR Lens mount ADAPTER FOR Hasselblad to S2 - ebay.com
       
      Es ist nur noch eine Frage der Zeit, wann andere Hersteller auch einen anbieten.
       
      Vielleicht bietet Zeiss auch Objektive mit dem S-Bajonett an.
